HYDRANT.

SPECIFICATION forming part of Letters Patent No. 353,217, dated November23, 1886. Application filed August 20, 1886. Serial No. 212,164. (Nomodeh) To all whom it may concern."

Be it known that I, EKINs HAND, a citizen of the United States, residingat Rochester, in the county of Monroe and State of New York, haveinvented a certain new and useful Improvement in Hydrants; and I dohereby declare that the following is a full, clear. and exactdescription of the same, reference being had to the drawingsaccompanying this application.

The object of my improvement is to prevent the accumulation of water andthe consequent freezing, and also to facilitate the attachment of hose;and the invention consists in the construction and arrangement of partshereinafter described and claimed.

In the drawings, Figure 1 is a central vertical section of a hydrant,showing my invention, the middle portion of same being broken away. Fig.2 is a cross-section of same in line 00 as of Fig. 1. Fig. 3 is anenlarged plan view of the bottom plate of the hydrant, showing the valvearrangement.

A indicates the top and B the bottom portions of the hydrant, which areof usual form, and are connected by a hollow trunk, which is shown asbroken away.

0 is the induction-pipe leading from the main, and D is a discharge-pipeat the bottom, leading to a sewer and serving to discharge the wasteWater, as will presently be described.

My improvement is as follows:

E is acylinder forming a cut-off, which rests A inside the barrel of thehydrant,at the bottom.

This cylinder is made hollow and open-ended at both ends, and it ismoved up and down by means of a rod, G, attached to it by a bail orarch, H, said rod extending up to the top of the hydrant,and providedwith a screw-thread that rests in a long threaded nut, I, which hasrotary but not vertical movement. When the cylinder ss raised above theinduction-pipe O, as shown in Fig. 1, the water passes up through thehollow cylinder to the top of the hydrant and rests under pressure, andis in condition to be discharged through the nozzles; but when saidcylinder is forced down below the induction-opening it cuts 011' thesupply of water, and such water as remains in the hydrant passes downthrough the hollow cylinder,and is discharged through the discharge-pipeD at the bottom by means of the valve arrangement presently to bedescribed.

J is the bottom plate of the hydrant.

K is a frame or bearing attached to said bottom plate, and provided witha central cylindrical seat,a,in which rests a cylindrical valve, L,having a square lower end, which rests over the opening b, thatleads tothe discharge-pipe. The joint is preferably ground to make a close fit.The upper end of the valve is provided with a screwstem, c, by which arod with a screw-socket can be inserted down through the hydrant at anytime to remove the valve. The valve is also provided withradially-projecting studs 01 d, which restin slots f f in the sides ofthe valve-seat, to prevent the valve from turning out of position withthe raising devices.

9 gare pins resting in sockets under the studs d d, and pivoted to thelower ends of rock-arms h h. The outer ends of these arms are elevatedand rest in such position as to be struck by the rim of the cylinder Ewhen pressed down to the bottom of the hydrant.

It will be seen that when the cylinder is raised the induction-waterwill be admitted and the discharge-valve will be closed, and when thecylinder is forced down the supply will be cut offand the waste-valvewill be opened. By this meansall the water can be discharged from thehydrant and there will be no danger 'of freezing. It obviates thecollection of water in the bottom of the hydrant. which occurs where awaste-hole is simply used some distance above the bottom, as in commonhydrants.

M M are the nozzles for the discharge of the water at the top of thehydrant. As many of these may be used as desired, two being shown in thedrawings.

N N are rods used in connection with the nozzles to cut off the flow.Each of these rods has a head, z, inside the hydrant, provided with apacking, is, that shuts against the inner end of the nozzle, also astem, l, that slides in a bearing, m, of the nozzle, to keep the valvein position. The central part of the rod is slotted, as shown at n, thisslotted part embracing the piston-rod G and allowing sulficient endmovement for the valve to open and close. At the rear is ascrew-threaded stem, 0, which screws into an elongated nut, 19, turn-ICO ing freely in a seat in the opposite side of the hydrant from thevalve, but having no end movement. By turning this nut the valve can beforced in to close againstthe end of the nozzle or drawn back to openit.

1* is a closed cap that screws on the outer end of he nozzle. The forkedportion n of the valve-rod allows he passage of the piston-rod G, andthis piston rod prevents the valve-rod from turning as the nut is turnedto open or close it.

By the means above described the valves that control the nozzles can beopened and closed from the opposite side of the hydrant from the valve,and in attaching a hose it is only necessary to remove the outercoveringcap, screw the hose on, and then open the valve; and a hose canbe applied to any one of the nozzles without affecting the others, whichin many hydrants cannot be done.

Ihe cylinder E is provided with metallic packing-rings s 8, similar tothose in use on the pistons ot'steam-engi nes.

Having described 1nyinvention,whatI claim as new, and desire to secureby Letters Patent, 1s

1. Ina hydrant, the combination ofthe openended cylinder,formingacnt-off to the inductionrwater, the valve covering the dischargeopeningat the bottom, said valve provided with radially-projecting studs, thecylindrical seat in which the valve rests, the verticallyacting pinsresting under the studs of the valve, and the rock-arms to which thepins are pivoted, said rock-arms standing in position to be struck bythe cylinder in descending, thus tripping the valve, as set forth.

2. In a hydrant, the combination, with the dischargenozzle, of avalve-rod constructed with a valve which shuts against the inner end ofthe nozzle, aforked central portion that enibraces the piston-rod, aguide-stem that rests in a bearing of the nozzle, and a screw-stern thatenters a nut on the opposite side of the hydrant from the valve, asherein shown and described.

In witness whereof I have hereunto signed my name in the presence of twosubscribing witnesses.
